AceShowbiz - Sharon Osbourne has ruled out a role on Simon Cowell's "The X Factor (US)" show, because the music mogul thinks she's too opinionated. Cowell has lined up British pop star Cheryl Cole and producer-record label boss Antonio "L.A" Reid as judges on his new American TV talent show venture, and reports suggest The Pussycat Dolls star Nicole Scherzinger is a favorite to host the show.

That means there's one more space for a celebrity judge, and Osbourne knows it won't be her or daughter Kelly Osbourne.

"I think Simon would have the same opinion about Kelly that he does of me, that we're both too opinionated," she tells HollyScoop. "I think he had enough of me [and] I don't think he wants to take on another Osbourne."

The rock matriarch, who was a judge on Cowell's British version of the show, thinks the music mogul should reteam with his former "American Idol" panelist Paula Abdul. She adds, "I think Simon should take Paula because they work so well together and they've got great chemistry."
